Sister Mary Helen and her Irish friend, Sister Eileen, need some R&R away from the pressures of their inner city vocation. A week at the idyllic St. Colette’s Retreat House, snuggled amid towering redwoods 65 miles from San Francisco, sounds like heaven. Unfortunately the muddled sisters mistakenly arrive a week too early and find that St. Colette’s is hosting a convention of hard-drinking, high-spirited priests. And when the serenity is further shattered by the murder of a former seminary student, suspicion falls on the holy fathers. But Sister Mary Helen has another theory about the perpetrator, and in her inimitable way she intends to uncover the deadly secrets and passions that the flesh is heir to.
